Purpose of Review <p>Since the term Tourettic OCD (TOCD) was first introduced, a growing body of research has investigated the ways in which chronic tic disorders like Tourette Syndrome (TS) and obsessive-compulsive disorder (OCD) overlap versus remain distinct. This brief review attempts to delineate findings across phenomenology and neurobiology as well as the implications results hold for TOCD assessment and treatment.</p> Recent Findings <p>Clinically, along with earlier age of onset and male predominance, the hallmark of TOCD is complex repetitive behaviors that blend premonitory sensations distinctive of tics with the “just right” anxious drives found in OCD. Neurobiologically, TOCD likely arises from dysfunction in the cortico-striato-thalamo-cortical (CSTC) circuits with neuroimaging indicating distinct but overlapping circuitry involvement compared to TS and OCD alone, adding credence to TOCD as a unique entity. Current assessment recommendations emphasize the flexible integration of established evidence based tools for TS and OCD with newer instruments that assess the range and purpose of sensory phenomena. Similarly, interventions for TOCD benefit from the blending of behavior and pharmaco-therapies for tics and OCD, with the goal of flexibly adapting techniques in an individualized manner.</p> Summary <p>Taken together, current research indicates a growing recognition of TOCD as a distinct disorder with unique clinical characteristics and neurobiology. Optimal assessment and treatment approaches are still being developed with current recommendations being multi-modal in nature. Future directions point towards work on establishing formal diagnostic criteria and specific and tailored assessment and treatment protocols for TOCD.</p>
